I remember reading this article when I was younger, and even then it struck me as something controversial. You can't defend freedom with anti-freedom tools, you can't fight fire with fire. Your desire to keep copyleft turns you into a corporate supporter :thinking:
I don't think so, anymore than public domain is a double standard, because they are two separate, but related things.
There should obviously be restriction on copyleft to prevent abuse, but the big thing is that a work put under copyleft should be forever in copyleft (like public domain), but that derivative works are *ALSO* forced into copyleft, with no prohibitions on commercial use. This is different than public domain, where derivative works are not forced to also be public domain.
In my opinion, copyleft better serves the copyright clause in the US Constitution "To promote the Progress of Science and useful Arts", better than copyright does.
The actual mechanics of making such a law are better suited to people with extensive experience with both copyleft and law.
Copyleft is currently a very clever hack of copyright, and thus is dependent on the continued existence of (and perpetual expansion of ) copyright terms.
If copyright had its own section of law, then copyright could be modified without adversely affecting copyleft.
But as you point out, the corporations like this state of affairs, because it gives them a convenient club to beat people that would otherwise support revisions to copyright with.
It is already enshrined at the same level as copyright, because it uses the same logical basis "the author of the work can dictate what you can and cannot do". If a corpo is caught using copylefted code in a non-free project, they will face legal consequences.
But corpos actually benefit more from this situation, as most of the software is nonfree, plus they have endless money to spend on lawyers, unlike free software people.
